 # Speech_Emotion_Detection
 
+   Emotion detection is a new research era in health informatics and forensic technology
+.Besides having some challenges ,voice based emotion recognition is getting popular .As
+the situation where the facial image is not available ,the voice is the only way to detect
+the emotional or psychiatric condition of a person. 
+However ,the voice signal is so dynamic even in a short-time frame so that ,a voice of the same person can differ with in
+a very subtle period of time. So there is a need to detect emotion of the person through
+his/her voice. It detects five emotion states from person’s voice (happy ,angry ,fearful
+,sad ,calm). Some of the applications where we can implement this include call centers
+to redirect to a person when one is angry ,smart car slowing down when one is angry or
+fearful.

 This repository contains my work on speech emotion detection using  <a href="https://zenodo.org/record/1188976#.Xl-poCEzZ0w" > RAVDESS</a> dataset.
 
 The models which were discussed in the repository are MLP,SVM,Decision Tree,CNN,Random Forest.
